(music) A bass guitar technique of hitting a string hard with the side of the thumb knuckle, producing a loud but brief snapping sound. Slapping is usually combined with popping, the act of pulling a string outward with the finger tip and letting it snap back. Invented by Larry Graham (Sly and the Family Stone, Graham Central Station).

Slap & pop bass sounds are very characteristic of disco and funk music, though around 1990 it got very popular again when bands like Red Hot Chilli Peppers, Primus, Infectious Grooves, and Faith No More hit the hard rock radio stations and Mtv.

Jazz players on upright bass (aka double bass) have a technique called "slapping", but it's a completely different technique that involves literally slapping the strings.

The ultimate drinking game. Played by at least three people sat in a circle. The game begins with everyone chanting the following: 'Whats the name of the game? Slaps. Whats the object? To get fucked.'
The person that starts in number 1 must shout out '1' while tapping either their left shoulder or their right shoulder. Whatever shoulder is tapped that is the direction the play goes so the next person is number 2. This continues until you get to number 7. Whoever is number 7 must place one hand over the other and the top hand decides the direction. Number 8 and 9 are the same as before but on number 10 you must point to someone who then has to drink for then has to drink for 10 seconds. If someone messes up before that they must drink for that number of seconds.

Billy, Bob and Timmy (Shouting together): Whats the name of the game? Slaps! Whats the object to get fucked!

another word for "flip-flop" sandals. the term will mostly be used in beach communities where the usual foot attire is a flip-flop. the term likely originated due to the "slapping" noise the shoe makes as one walks down the street.
